Hi
I am not going to be a lot of help, but we have tried solar spotlight and regular spotlights and put the colored bulbs and put at the bottom of some of our plants. I hope you get some good answers as I would also be interested. On any shows I have watched they same move them around at night until you get the desired effect. I get this newsletter and a lot of good ideas P. Allen Smith [gardenletter@lb.bcentral.com]
Troy-Joan@att.net if you get any good answers.
Thanks
Joanie

Not to appear a dummy, but I have a small string of the clear rope lights tucked under my Hosta. It looks really well and is very very faint, glows more than lights. That is what I wanted. I do not have a clue how to help you with lighting a really large area with them..without making them look like "Christmas Lights". I have put a string of Rope lights in a large wrought iron urn and it cast a pretty sheen on and around some landscaping. Have not tried them in a solid (concrete) urn but that may be the very "trick" you are seeking.
Hope this helps.
